Application filed March 1?, 1924, Serial No. acacia paratns.

The principal object of the invention is to provide means for detachably engaging the audio to its atom in a firm and secure manner,

Another purpose is to produce means for positive engagement that permits axial justment of the handle relative to the stem and which avoids the use of set screws and like objectional elements. A further aim is' in the provision of an adjustable couplin chen 1y constructs easily applied and which presents a neat and attractive appearance.

These and analogous aims and objects which will later appear, are accomplished by the novel construction, combination and arran ement of parts hereafter described and. s own in the accompanying drawing, forming a material-part of this disclosure, andin whicliz- Figure 1 is a side elevational view of a conventional type of stem handle, parts being shown in section.

yinthe iormofasmallwheoha s Hot, Cold, Shower, and so fort the mature at the liquid oontrolle device that can be' log: the valve and it is obviously desirable t at the word or symbol used he so disposed as to be clearly and unmistakahly read, par ticularlywhen the valve is closed, that to say the word should be level and right side up. 4 This condition precludes having a label bearing handle fixed to the valve at random, for the reason that there is no as surance as to the position the word or mark may assume when-the valve is closed. and

further, the position of the stem may vary from time to time, due to resenting or repacking of the valve, rendering relative adjustment highly important.

Such adjustment is usually made by fitting the hand wheel or handle to the stem, coinmonly reduced at itsoutcr end and fro quently ribbed or corrugated, and held in. adjustment by asst-screw Such setscrews interfere with'the fingers of a person operating the handle, often causing minor impulse and are always unsightly,-

besides fr uently failing to hold, perhaps at a critics moment. 1

- The present invention avoids all such un-' till inga neat and secure, ad'ustable but positive connection as .will now. set forth Referrin more in detail to the drawing,

the numera 15 designates in general a valve stem having the usual operative elements not shown at its-lower end and being revoluble' in'' the body of the valve as \Vl'll be' -clearly understood.

The upper amid the stem, as shown in Figures 1 and 4, is reduced in diameter and provided with a screw-thread 16, and has a shortintermediate squared portion 17.

The handle element, generally designated. by the numeral 18, is composed of a body 19, havin a plurality of extensions, equally space and terminating in spherical members .20 adapted to be firmly grasped by the hand of an operator in actuating the valve.

A dome shaped element 21 is raised from the body 19, at its center and set rigidly in the same is a panel 22 hearing an inscription 22' denoting the purpose of the valve or the material it controls.

Extending from the op osite, or lower side of the body 19 is a hu 23 having on its exterior a screw-thread Maud containing an axial screw threaded opening 25, the same .being suited to receive the threaded portion 16 of the valve stem.
